Is an arc magnet pricelist the same as a supplier quote?

No. It is a budget table with quantity tiers and assumptions. A supplier quote must confirm drawing, process, tooling, inspection, delivery, and commercial terms.

Why does this page generate sample, pilot, and production tiers?

Setup, tooling, yield, and inspection costs are allocated differently by quantity. Separate tiers prevent one row from hiding the real commercial comparison.

Can public catalog prices be used directly?

Only when OD, ID, arc angle, length, grade, coating, magnetization, and MOQ match the catalog SKU without redesign.

How is this different from the arc magnet price estimator?

The price estimator produces one budget band. This pricelist page builds a tiered quote table and focuses on supplier comparison, evidence gaps, and landed-cost assumptions.

Arc magnet pricelist tool + report

Arc magnet pricelist builder for quote-ready tier tables.

Build a sample, pilot, and production price-list range before sending an RFQ. The result separates visible catalog signals, custom quote assumptions, evidence gaps, and landed-cost risk.

Report summary

The pricelist answer is a table plus evidence, not a single published price.

Search results show that public arc magnet prices exist for catalog SKUs, while custom motor arcs depend on drawing, grade, coating, magnetization, quantity, and destination assumptions.

A useful pricelist has tiers, not one number

3 rows minimum

Sample, pilot, and production quantities should be separated because setup, tooling, yield, and inspection are allocated differently.

S2-S4

Public price visibility is narrow

Catalog-only

Visible web prices are valid only when geometry, magnetization, grade, coating, and quantity match the SKU.

RFQ evidence changes comparability

5 evidence gates

Drawing, grade, coating, magnetization, and test method must be visible before supplier price rows can be compared.

S3, S4, S6

Landed cost can beat unit price

2026 tariff signal

U.S. or EU destination assumptions should be priced separately from ex-works magnet cost.

S7, S8

Raw-material data is a risk signal, not a quote

390,000 t REO

USGS 2025 rare-earth mine-production data explains supply exposure, but it cannot be converted into a verified NdFeB arc magnet pricelist.

Contract clauses can override a cheap row

DFARS 2027 step-up

For covered U.S. Government work, origin and production-stage evidence may matter before recurring unit price.

Research enhancement

What the second evidence pass added, and what remains unproven.

This audit turns vague price-list claims into dated, source-backed decision checks. It also labels the places where public evidence is not enough to create a purchase-ready conclusion.

Separate unit, landed, evidence, and clause rows

Audited gap	Information added	Decision use	Boundary / 待确认	Source
Public catalog evidence was described but not quantified	June 13, 2026 catalog snapshots show SKU rows with price, stock, dimensions, grade, plating, pole split, and MOQ, including M0404 and M5035 examples.	Use catalog rows as prototype benchmarks only when the SKU geometry and magnetization match.	A catalog snapshot cannot prove a live custom-market price or production tooling allocation.	S2
Rare-earth risk lacked dated magnitude	USGS 2026 reports 2025 world rare-earth mine production of 390,000 metric tons REO, including 270,000 metric tons REO from China and 51,000 metric tons REO from the United States.	Ask suppliers to state quote validity, grade basis, and heavy rare-earth exposure instead of ranking by unit price alone.	REO mine-production data does not equal NdFeB magnet output, dysprosium/terbium availability, or supplier piece price.	S5
Policy risk was present but not classified by applicability	USTR confirms 2026 Section 301 timing for permanent magnets under HTSUS 8505.11.00; DFARS confirms separate covered-material rules for some U.S. Government contracts.	Separate ordinary commercial landed-cost review from contract-clause review in the price list.	The page does not provide customs, sanctions, or contract legal advice; buyer counsel and broker confirmation are required.	S8, S9
Evidence standards were not tied to what they cannot prove	IEC 60404-5 supports magnetic measurement language, but it does not publish a universal premium for curves, flux checks, or certificates.	Price magnetic evidence as a separate supplier response column.	Testing scope must be selected by the buyer and supplier for the application duty cycle.	S6

Evidence discipline

The page now treats public catalog rows, standards, USGS supply data, EU policy, USTR tariff timing, and DFARS procurement clauses as different evidence types. They answer different questions and should not be collapsed into one price number.

Methodology

How the builder turns inputs into price-list rows.

The model is deterministic. It converts arc geometry into approximate volume, applies material and evidence factors, then allocates quantity tiers and uncertainty separately.

Builder flow

Cost bridge

Input	Rule	Boundary
Arc geometry	Volume from mean diameter, arc angle, radial thickness, and length	Does not replace CAD, chamfer, tolerance, or yield review
Material and grade	Material baseline multiplied by standard, high-temperature, or high-Hcj grade factor	Public evidence supports direction, not exact supplier surcharge
Quantity tiers	Lower tiers carry higher allocation; production tiers reduce recurring unit basis	Supplier capacity and tooling reuse can reverse the expected trend
Evidence level	Catalog, drawing, and validated-sample levels change confidence and price scope	Validation evidence costs more but reduces false comparison risk
Destination	U.S., EU, or unknown destinations widen landed-cost assumptions	Tariffs and compliance must be confirmed by buyer customs and legal review
Policy and contract scope	Tariff and procurement-clause questions are flagged separately from unit price	The builder does not classify goods, determine origin, or decide whether DFARS clauses apply

Model assumptions that still require supplier confirmation

The builder provides a reproducible budget range, but these fields remain 待确认 / not reliably available from public data.

Live custom NdFeB, ferrite, SmCo, or Alnico arc magnet price by supplier

Supplier-specific yield loss, fixture ownership, and process scrap

Final HTS classification, origin determination, tariff exclusion, or duty liability

Whether a government procurement clause applies to a private commercial RFQ

Actual heavy rare-earth content, dysprosium/terbium exposure, and quote validity

Final magnetic test package, acceptance limits, and production release evidence

Evidence layer

What public evidence can and cannot prove.

The source table is dated because price visibility, tariff timing, and raw-material context can change. Unknown values are marked as assumptions instead of turned into fake certainty.

Public evidence boundary table

These boundaries prevent a public source from being stretched beyond what it can verify.

Question	Can prove	Cannot prove	Buyer action
Can a public catalog row prove price?	A dated SKU price, stock signal, MOQ, and listed geometry.	Custom tooling, arc yield, fixture ownership, coating qualification, production lead time, or landed cost.	Keep catalog rows in a prototype benchmark column, not the production quote column.
Can a supplier product page prove quote readiness?	Which variables the supplier expects, such as size, angle, grade, coating, and magnetic orientation.	The supplier price, capacity, yield loss, inspection burden, or final delivery term.	Use the variable list to complete the RFQ before asking for tiered rows.
Can standards prove a price premium?	Measurement vocabulary and test evidence categories for permanent magnets.	A universal surcharge for a demagnetization curve, flux map, certificate, or PPAP-style package.	Request evidence scope as named options, then compare supplier premiums line by line.
Can policy sources prove landed cost?	Applicable dates, benchmark targets, and tariff or contract risk questions.	Your final HTS classification, origin determination, exclusions, Incoterms, or duty liability.	Ask the supplier for origin and trade data, then have a broker validate before award.

Policy and clause applicability checks

U.S., EU, and contract-clause signals change different parts of the price list. They should be routed into separate columns instead of hidden inside unit price.

Trigger	Verified signal	Do not assume	Price-list action	Source
U.S.-bound metal permanent magnets from China	USTR identifies permanent magnets under HTSUS 8505.11.00 and a 2026 Section 301 rate increase to 25 percent.	Do not apply one tariff result to every material, assembly, origin, exclusion, or statistical suffix.	Require origin, HTS basis, Incoterms, and duty responsibility as separate price-list columns.	S8
EU destination or EU-regulated program	The EU CRMA sets 2030 benchmarks: 10 percent extraction, 40 percent processing, 25 percent recycling, and no more than 65 percent from one third country.	The benchmarks are not a per-piece price adder and do not prove supplier traceability.	Ask whether material origin, recycled content, or dependency reporting is required for the program.	S7
U.S. Government or defense contract clause	DFARS 252.225-7052 covers NdFeB and SmCo magnets and names covered countries including China, Russia, North Korea, and Iran.	This is not a blanket rule for every private commercial purchase.	Add clause applicability, covered-material attestation, and production-stage origin evidence to the RFQ.	S9

Competitor and alternative paths

A price list can come from four different buying paths.

Catalog pages, marketplaces, direct manufacturers, and engineering distributors answer different versions of the query. The right comparison depends on evidence depth.

Path	Price signal	Best for	Weakness
Public catalog listing	Visible SKU price, MOQ, and stock count	Prototype fit checks and urgent bench builds	Weak for custom motor arcs, high temperature, or qualified coating
Marketplace quote request	Fast supplier responses with wide quality spread	Early supplier discovery when evidence is still incomplete	Unit price may exclude tooling, magnetic evidence, and landed cost
Direct manufacturer RFQ	Drawing-driven recurring and non-recurring quote lines	Pilot and production-intent motor programs	Slower if drawing, magnetization, coating, or test scope is missing
Engineering distributor	Higher service content and application review	High-speed, high-temperature, or regulated programs	Can look expensive if compared only on piece price

Risk limits

Where an arc magnet pricelist can mislead.

The risk layer explains when a cheaper row is not actually comparable and gives a mitigation action for each failure mode.

Risk matrix

Risk	Probability	Impact	Mitigation
Catalog row reused as production price	Medium	High	Keep catalog rows in a separate prototype section and request tooling, fixture, and inspection lines for production.
Magnetization direction missing	High	High	Attach pole pattern and field direction drawing before accepting any price list row.
Heavy rare-earth exposure hidden	Medium	High	Ask suppliers to state grade, Hcj basis, temperature assumption, and quote validity period.
Landed cost omitted	Medium	Medium	Separate ex-works price, freight, Incoterms, origin, HTS, tariff responsibility, and destination documents.
Dimensional-only quote compared to validated quote	High	Medium	Label certificate, coating, magnetic curve, flux, and PPAP-style evidence as separate line items.
Policy rule applied to the wrong scope	Medium	High	Split commercial landed-cost checks from DFARS or other contract-clause checks, then confirm HTS, origin, and clause applicability with the responsible specialist.
Raw-material statistics treated as piece-price data	Medium	Medium	Use USGS and policy data to set risk questions, not to calculate a live unit price without supplier quote evidence.

Scenario examples

Use the pricelist differently by buying stage.

These examples show how the same table changes meaning for catalog benchmarking, pilot RFQ, production comparison, and landed-cost review.

Visible catalog benchmark

12-48 pieces, catalog geometry, standard NdFeB, known magnetization

Use public list prices as prototype evidence, then move to RFQ only when one field deviates.

Pilot motor RFQ

1,200 pieces, new tooling, drawing available, high-temperature NdFeB

Request a three-tier price list with tooling, coating evidence, magnetic evidence, and sample lead time separated.

Production quote comparison

48,000 pieces, heavy rare-earth grade, EU destination, fixture unknown

Hold supplier ranking until sourcing, traceability, magnetization fixture, validation, and landed-cost lines are confirmed.

U.S.-bound China-origin risk

Custom NdFeB arcs, low ex-works unit price, duties excluded

Compare landed cost separately and require origin, HTS, Section 301 exposure, Incoterms, and quote validity in the price list.

Defense or U.S. Government clause screen

NdFeB or SmCo arcs for a covered program, supplier offers a low offshore unit price

Do not rank the row until DFARS or contract-flowdown applicability, covered-country exposure, and production-stage evidence are confirmed.

RFQ table

Minimum columns for a price list you can compare.

If a supplier omits a column, mark it as not available and ask whether it is excluded or included elsewhere.

Quantity tier and quote validity date

Recurring unit price by material and grade

Tooling, mold, and magnetization fixture cost

Coating, corrosion, and adhesive-process evidence

Magnetic test method, curve, flux, or certificate scope

Sample lead time and production lead time

Origin, Incoterms, HTS/customs assumption, and tariff responsibility

Contract clause applicability, covered-material evidence, and covered-country screen

Packaging, destination market, and compliance documents

Drawing revision, tolerance, chamfer, and inspection plan
